Polyxeinos the Seafarer

Polyxeinos the Seafarer (died 431 BC) was a Spartan naval captain during the Peloponnesian War. In 431 BC, his ship was stationed off the coast of Attica to prevent an Athenian supply ship from making a run to Mytilene, but the mercenary Kassandra and her ship Adrestia succeeded in immobilizing and boarding Polyxeinos' ship during the Battle of Dicastica. Kassandra then proceeded to slay Polyxeinos and his crew.
